Game of Thrones averaged 743,000 viewers and peak viewing of 823,000 in its Monday night premiere in the United Kingdom. That tops Sky Atlantic's previous high (438,000) for Boardwalk Empire. So, whileBoardwalk Empireis the far bigger "hit" in the U.S., GoT takes the crown in the U.K. Not much of a surprise perhaps since it seems every actor in Game of Thrones is from the U.K.
